Patented dimly h, lddth application tiled ltovemhcr a, with, serial No. titted. Renewed November as, 1919, serial he. states.

To all whom it may concern:

Be it known that l, Cam, Sonatina, a suhject ot the German Emperor, and residing at lldehlis, in 'llhnringia, Germany, have invented certain new and usetul limprovements in 'llypewriting-Machines, of

a which the lollowing is a specitication.

add

'lhe present invention consists in im provements in typewriting-machines in which a motor or the like is employed for actuating the type-hars and especially that hindol machines in which the mechanically driven means consists in a continuously rotating shalt as described in my ap.

plication Serial No; tidlh'l tiled Flovemher em, 1915, wherein the printing action is immediately 'ed'ected hy the rotating shalt,

The improvements torming the subject matter of the present invention consist in the mechanical drive not necessarily heing eflected by a rotating shalt and the means serving tor said mechanical drive must not he in continuous rotation hut may he pe riodically moved. Finally provisions are made through which the type-levers may also he actuated immediately, as descrihed in the atorecited application, whereby the mechanical means eitect the return-move ment oi the type-levers trom the platen, in the latter case the mechanical drive may have a rotating, an oscillating or a straight line movement and may he continuously or periodically moved,

further improvement consists in an interlocking device, which serves to malre the writing with the present machine accurate, as by the quickness oi the play ol the lreys it may easily occur that a wrong lrey may he touched which must-he avoided.

lhe present invention is schematically represented in the annexed drawings, wherein:

F ignre 1 represents an arrangement according to my application Fserlal Flo. 6015? mentioned above with the diillerence that the rotating shalt is provided with two noses" Fig 2 shows the oscillating drive of the machine;

Fig. 3 the straight lme drive;

in the said Figs. 1, 2 and 8 the movement of the mechanical drive is continuons.

,Figs. d and 6 represent the periodical rotation of the mechanical-means namely:

Fig. 4 with a rotating shalt,

Fig. 5 with an oscillating shaft and F g. 6 with a straight-line movement; it igs. 7 to 12 represent the arrangement with a reversed movement,

l igsi to with a continuously moved mechanical drive,

' Figsld to 12 with mechanipal drive:

it 1gs. l and it) show the arrangement with a rotation movement,

. Figs. 8 and 11 the same with an oscillatmg movement,

a periodically moved till Figs. 9 and 12 the same with a straightline movement,

in actuating the hey-lever l :tulcrumed at 90 (Figs. 1 and 2) the spring 2 pulls the linlr 3 downwardly, this hair heing journaled on a carrier 91, which is revolnhly mounted on a stud 92 on the hey it. Simultaneohsly the nose 4t of said linlr 3 draws therod 5 into reach of the rotating shaft 6, 'llh s shaft is provided with part 7 in Fig. 2 which strilies against a nose 8 of said rod 5 and throws the same in forward direction,-

wherehy the type-lever 9 actuated by connecting lever 94 is moved against the printing platen. in Fig. l the rotating shalt ti has two projections 93 acting in a similar manner to part 'i' in Fig,

in the meantime the nose l has released thenose 10, so that the spring ll is able fir'stly to draw the type-lever 9 haclr into its position of rest and secondly 'to draw the rod 5 upward. lilerehy the nose it comes into engagement with nose l of the rod The shaft h in Fig. 2 receives a continuous oscillating movement from the connecting rod 12'.

ln Fi 3 the working is the same as in Fig. 2, t e only diflerence consisting in the mechanical drive heing ellected by an endless chain, 13, which is provided with noses ltwhich strike against the nose l5 ill tltl

of engagement with the shaft 28, whereafter the latter moves freely. Simultaneously the lever 33 has made a downward movement with the part 34, whereby the nose 35 pulls the rod 31 downwardly, so that the nose 30 drops down into the path of the part 29 which thereupon throws the rod 31 in forward direction, the latter throwing the type lever 32 against the platen. After the completion of the printing action the springs 36, 37 and 38 draw the respective parts. back into their position of rest.

In the arrangement represented in Fig. 5 the drive is effected by a connecting rod 39. A fter releasing the nose 40 the part 41 as before throws thei'od 42 in forward-direction and with it the type-lever 32 against the platen.

As soon as the clutch 43 (see Fig. 6) has released the drive 44, through the depression of key 20, the endless chain 46 provided with the noses moves on and throws the type-lever against the platen as soon as the nose 47 of the rod 48 comes into the reach of one of the noses 45.

The F 7 to 12 show the reversed arrangement of Figs. 1 to 6.

The Figs. 7 and 9 show the arrangement with the continuously moved drive and the Figs. 10 to 12 with the periodically moved drive.

In actuating the key-lever 49 again fulcrumerl at 90, (Fig. 7) the rod 50 and with it the rod 51 is pulled downward. This becomes possible as soon as the nose 52 en gages the respective gap of the shaft 53. Hereby the spring 54 comes into action and throws the type-lever 55 against the platen.

As soon as the. nose 56 has come into reach of the part 57 of the continuously rotating shaft 58 the rod 51 is thrown backward and the type-lever 55 returns in its position of rest.

Fig. 8, otherwise similar to Fig. 7, rep- !resents the oscillating movement effected by a connecting rod 59 from a motor 95.

In Fig. 9 the endless'chain 60 rolls over the rollers 61, 62 and the noses 63 strike against and push the projection 64 of the rod 65 back whereby the type-lever 55 returns in its position of rest.

Otherwise the construction is similar to that shown in Figs. 7 and 8, shaft 53, however, is here provlded with two notches.

The Figs. 10 to 12 represent the arrange- 'ment with a periodically operating drive.

In actuating the key-lever 68 (Fig. 10) the rod 69 and with it the rod 70 is pulled dowriward. Hereby the end 71 strikes against one of the arms of the two-armed lever 72,- whereby the finger 73 comes out of engagement with the shaft 74 and the latter is rotated. In actuating the key-lever 68 the rod 75 and with it the rod 76 is simultaneonsly drawn downward. Hereby the printing action of the type-lever 77 against the platen is effected.

Meanwhile the nose 78 has come into the reach of the projecting part 79 on the shaft 74, whereby the latter pushes the nose 78 and-the rod 76 back, so that the type-lever returns in its position of rest. Springs 80, 81 and 82 withdraw therespective parts after their printing action in their position of rest.

In Figs. 11 and 12 the working is exactly the same only the drive is in Fig. 11 effected by the connecting rod '83 and in Fig. 12 by the endless chain 84 provided with noses 85.

In Fig. 11 the part 86 pushes against the nose 87 of the rod 88, whereby the typelever 77 returns in its position of rest. The same effect is in Fig. 12 obtained by the nose 85 pushing against the nose 87 of the rod 89.
